Rear brake pad change

[Benlake]

Hi please can anyone help? I was using the little piston tool to push back the piston on the rear brake caliper. It was pretty stiff but was going back, then it ripped the little rubber boot that sits around the piston. I had the handbrake off but it was still connected. Should I have disconnected it and does anyone have any advice on what to do with the caliper

You can get service parts here;

Sounds like the piston is rusty and seized. If you are in a hurry to get it back on the road then you could get the refurbished caliper or otherwise just get the service kit?

Or @bigbear007 runs a calliper repair service.

Thanks - I had mine refurbished 6 months ago which is annoying as it would have been cheaper to buy the whole caliper
The piston pushing tool locks into the end of the piston and twists, I think it was the twisting that ripped the boot. Or should the standard tool have just pushed them in with out issue.

Just so I don't wreck the next ones!

As in should the piston just push back into the caliper without feeling really stiff just using the standard tool. Think I will buy a refurbished set.

On rears def a wind in rather than a push.
Might the boot have got trapped between tool and piston.
For a caliper that has been refurb'd. Sounds rather stiff. Certainly some resistance but should wind back smoothly.

A shot in the dark but was the bleed screw open?

[Benlake]

Bleed screw was closed but the boot he put on is different to toyotas, and when it twisted it ripped. I think maybe better to go with refurb caliper rather than throw good money after bad. Wish Id done that first time round

There have been lots of comments about garages messing up these rear brakes, it definitely pays to have someone experienced work on your rear brakes/handbrake if at all possible.

@Benlake

What year is your car and where you based?

[Benlake]

Yeah I think the guy used bodgy boots . The front brakes are original and the pistons slipped back on those without any issues. Car is 2006 and Im based in Cheshire.

There will be a bit of resistance when turning to retract the piston, did you have to cap off the master cylinder when doing it ?

OK, I might have been able to assist, but no.

Thanks yeah had the cap off
